The 'common' library has been removed. The only project that actually
used it was metsrv, so the code that metsrv required from common is now
directly compiled in as part of that project.
The common folder now contains files that are importanta cross all of
the projects, with a primary focus on the new "API" style function. What
this means is that MetSrv has an API that it exposes through a function
pointer that is passed to the extension when it's initialised. This
pointer references a structure with all the API functions wired in. This
means that:
* Extensions don't need to know anything about metsrv at compile time.
* The delay loading code can be removed, which was one of the last
instances of "metsrv.dll" as a string.
* Metsrv.dll no longer exports any functions.
More to come.
This PR contains changes that will force Meterpreter binaries to be
outputted to "output" instead of the "output/<arch>" folders. So the gem
generation needs to be updated as well so that this new location is used
when generating the gem.
Added /MP for parallel builds, and removed precompiled headers as /Yc
isn't compat with /MP.
Not enabled for the Powershell extension because of it's .NET-ness.
This was a bit of a pain, but was well worth it. Had to add a couple of
hacks to make it all work, but this is a nicer solution than having to
depend on OpenSSL and its horrendous build experience.
Warnings as errors, builds clean. Had to do some horrible hacks:
1) Include custom implementation of a lib function just so we could
link against stuff built with older VS.
2) Include legacy symbols for old io for the same reason.
I found an edge case where stageless payloads did not work when they
were embedded in .NET applications. The reason for this is because the
configuration block is stored alongside the code in stageless payloads
and hence is loaded into memory as part of the section when it's mapped.
This section, in native world, remains RWX, and hence we don't have a
problem reading from and writing to it. We write to it for various
reasons, such as when the session guid changes.
In .NET land, this section is mapped as RX instead of RWX. This means
that when we try to write to it, the program segfaults due to an access
violation.
This code modifies the loading of the configuration so that instead of
maintaining a pointer to the original configuration, it instead creates
a copy of it on the heap. I preferred this fix over marking the memory
as RWX, which obviously stands out a bit more.
